From Leaves of Grass, by Walt Whitman:

No labor-saving machine,
Nor discovery have I made,
Nor will I be able to leave behind me any wealthy bequest to found a hospital or library,
Nor reminiscence of any deed of courage for America,
Nor literary success nor intellect, nor book for the book-shelf,
But a few carols vibrating through the air I leave,
For comrades and lovers.
